Admidio is an open-source user management solution. From version 5.0.0 to before version 5.0.8, Admidio relies on adm_my_files/.htaccess to deny direct HTTP access to uploaded documents. The Docker image ships with AllowOverride None in the Apache configuration, which causes Apache to silently ignore all .htaccess files. As a result, any file uploaded to the documents module regardless of the role-based permissions configured in the UI, is directly accessible over HTTP without authentication by anyone who knows the file path. The file path is disclosed in the upload response JSON. This issue has been patched in version 5.0.8.
